Is there a way to log the "Commanded" VE used during operation? What I want is to get a timestamped VE that get's used in the fueling calculations in every line (row) of the excel-based (.csv) output of a log. That way I can take the AFR % Error from the WB02 for each reading and calculate a "Corrected" VE.
The typical procedure of using the HPTuners histogram of AFR % Error and applying that to the VE table is causing my tunes to 'hunt' continuously...one day I'll add 2% to a given cell then another day i'll subtract 2% from a given cell, for example...doing some statistics on my logs is showing a bimodal distribution (2 humps in a histogram, instead of typically and hopefully, 1).
Here is an example of what I'm trying to do (see attachment which is an excel output of a log at idle)...however in the attachment the "Commanded VE %" is a calculation performed in Excel using the CylAirmass calculation inverted to find VE [VE=(CylAirmass*0.28705*((IAT+459.67)*5/9)*8cylinders)/(6*MAP)]...but there seems to be lots of error in this method so I need realtime data from the scanner...and the "Corrected VE %" is just "Commanded VE% x (1 - AFR Error %). For example in this cell of the VE table (30kPa,800rpm) my VE per the Primary VE table should be 55.92%.
